Restriction

Description

Sender ID

Sender IDs (the from address displayed on recipients’ phones) to be used must be pre-registered beforehand, along with the template of the message to be sent to India. Any message sent outside of these Sender IDs and message templates may be dropped before delivery and may still be charged to the sender.

To manage Sender ID in India, Clickatell sends all messages with a pre-approved six-digit alpha numeric sender. Numeric senders are not allowed.

National Do Not Call list (NDNC)

A substantial portion of mobile numbers are registered on the NDNC, and if you send marketing or promotional messages to these numbers, your message will be blocked (you can still send transactional and manually approved messages to these numbers).

Sender ID for transactional SMS messages must contain six alphanumeric characters and must be pre-registered.

Sender ID for promotional SMS messages: For promotional accounts, Sender ID will be replaced with assigned short code from the operator.

NOTE: No promotional content should be routed through the transactional route.

Time restriction

Promotional SMS messages may only be sent between 9am and 9pm standard India time. This means your messages could be blocked or delayed if you send outside of these times, depending on the operator.

Volume restriction

You may not send more than six messages per hour with the same content, from the same sender, to the same number

Restrictions on messages with stock-related information

Transactional routes cannot be used for sending any messages relating to stocks and/or shares. To use transactional routes for stock market activities, you’ll need to get certification from stock brokers and/or entities registered with the Securities and Exchange Board of India (SEBI).

The certification must follow the guidelines below:

Certification must be written on the entity’s company letterhead.

The entity should be registered with SEBI.

Entity should mention the command line interfaces (CLIs) to be used by them and the nature of the messages/content to be used.

Purchase order validity.

Restrictions on opt-in messages

No opt-in messages should be sent via
transactional routes.

An opt-in message can be sent to the end user
only if s/he has submitted a documented approval.

Web opt-ins are not accepted as approved opt-ins.

Restriction on social invites

Any invitations related to social media/websites/OTTs need to have their content confirmed and whitelisted prior to being sent via transactional accounts, and violating this can result in heavy fines.
